There's no such thing as a legal wetback. The term "wetback" is a direct reference to illegal immigrants that have to come across the river in order to get here. As such, it's pretty much nothing but a synonym for "illegal Mexican immigrant", however racist shitheads have destroyed the original meaning.

If that was more wide spread among the Arab community, we wouldn't need to be over in Iraq in the first place.

Okay, pet peeve of mine - How come people who couldn't find Iraq on a map (prolly cause they're looking for all them Iraqi Sikhs), insist on talking about "we" being in Iraq? Unless you've been boots on the ground, you're giving yourself too much credit by talking about how "we" are in Iraq.
